To withdraw from ICO wallet I simply need to create a new address in lite client and put the address to my ICO's wallet's Wave address box + confirm in mail, right?
Yep, mate and then just wait

And do not forget to save and check your seed code -
How can I check that I am using the correct seed?
Logout from Wallet. Click on Import account. Put your Seed code. Click on Generate address from seed. If you get the same address - You did everything right. Click on Back. Login to your wallet.
Thx mate, just want to be sure.
Now I'm going to check where can I check the status of withdraws

I'm pretty sure there is a big line before me.

ps: social media bounties still havent a tx id
